Noctua NH-L9i-17xx, 92 mm Low-profile CPU Cooler, Brown

The Noctua NH-L9i-17xx is an ultra-compact air cooler specifically engineered for Intel LGA1700 and LGA1851 processor sockets. Its primary function is providing reliable thermal management in space-constrained enclosures, such as Small Form Factor (SFF) cases and HTPCs. The cooler maintains a total installed height of 37 mm, ensuring complete compatibility with surrounding components like tall RAM modules and PCIe cards. This low-profile form factor is achieved through a densely packed heatsink combined with a dedicated slim 92 mm fan.

Thermal dissipation relies on a heatsink constructed from a copper base plate and nickel-plated aluminum fins, utilizing two integrated 6 mm heat pipes to transfer heat efficiently. The included NF-A9x14 PWM fan operates with automatic speed regulation, adjustable between 0 and 2500 RPM based on thermal load. Maximum noise output registers at 19.9 dB, while static pressure peaks at 2.11 mmH₂O. With a maximum rated capacity of 59 W TDP, the NH-L9i-17xx is suited for processors operating within designated power limits for compact builds.
